Commutation Setup
The Commutation dialog window allows you to define a motor’s commutation characteristics. Here you
specify motor commutation parameters, correction and initialization methods, and encoder positioning.
In the motor section, most of the boxes are calculations based on your selected motor parameters.
Select “Commutation…” on the “Setup” menu to activate the dialog shown below.
For initial setup most of the commutation screen can be ignored. For example, if Hall sensors are util-
ized they need to be selected under “Init Method”. Then, “Hall Edge” needs to be chosen as correction
type. Finally, “Number of Poles” and “Lines per Revolution” need to be entered (Rotary). Selecting lin-
ear instead of rotary will display parameters that are specific to a linear motor. Edit boxes that are not
available are values that are calculated based on other parameters entered. Encoder Scaling and Re-
mainder are automatically calculated based on the motor and encoder values entered. The working
column represents modified values that are sent to the amplifier when clicking the “Send Values to
Amp” button. In order to update the commutation values, the amp must be disabled. You can do this
by clicking on the “Disable/Enable Amp” button. All edit box parameters are described in the help dia-
log at the bottom right of the window. You can activate this dialog by clicking on it and then you may
scroll up and down through the help dialog with the up or down arrows. Press F1 to view the dialog
help text in notepad. After the values are sent to the amplifier you may test the values by enabling the
amplifier.
